This article was published in the newspaper The Daily Kennebec Journal, of Augusta, Main, USA, on April 19, 1908.
The article was found by the excellent researcher Chris Aubeck, and the interest is that it is the earliest discovered mention of Martians described as little green men in a newspaper.
The Martians were prepared to catch the first hommage from the earth.
"Let me see", exclaimed the first little green man, "I wonder of the first communication will be a flash, a tick or a knock."
"A knock, very likely", laughed the second little green man. "You know the Earth is full of knockers."
Which shows how wise the Martians really are.
